Lloyd's mother and other family members were sitting in their usual spots in the front row behind prosecutors on Thursday morning. His mother left the room ahead of Zane's testimony.

Defense lawyer James Sultan has previously said that he expects to present witnesses and rest his case on Monday.

Prosecutors have called more than 100 witnesses since testimony began on Jan. 29, including team owner Robert Kraft, who testified this week that two days after the killing Hernandez looked him in the eye and told him that he was innocent.

They also submitted hundreds of pieces of evidence, including surveillance videos from inside Hernandez's home that showed him holding a black object that appeared to be a gun less than 10 minutes after Lloyd's killing, and a marijuana joint found near Lloyd's body that had DNA from both men on it.

Hernandez's legal team has gone after that evidence, calling into question the testimony of an employee of weapons manufacturer Glock, who had identified the black object in Hernandez's hand as a gun, and arguing instead that it was an electronic device such as an iPad or a TV remote.

They also have gone after the police investigation, painting it as bumbling and inept and saying that Hernandez was targeted by police as a suspect because he is a celebrity.
